초록

A gas turbine engine in which a rotating component (such as a turbine shaft or disc) is cooled by directing preswirled air at it by flowing the air along a passageway defined by the rotating component and a static wall. To reduce the viscous drag on the swirling air due to the presence of the static wall, the static wall is transpired to cause the boundary layer of air adjacent the wall to move in the same direction as the swirling air. The wall may be transpired by sucking or blowing air through air passages through the wall.

청구항

In a gas turbine engine having a rotating component and a static wall positioned adjacent said rotating component to define a passageway, said engine having a main air flow, means for tapping pressurized air from said main air flow, means for preswirling said tapped air in the same direction as the direction of rotation of said rotating component, and means for directing the preswirled air onto said rotating component through said passageway, the improvement comprising: a plurality of passages through said static wall, said static wall comprising a perfo...
